Find copy-and-paste code - for bash / shell script

Question

I have a bash project, which consists a dozen files. There are some copy paste between the files (and inside one files also).

So, is there a copy paste detector for bash / shell scripts or at least for plain text?

Copy paste detector, like this, just for shell script: http://pmd.sourceforge.net/pmd-5.1.0/cpd.html

Similar question for java: Do tools exist which automatically find copy-and-paste code?

For Perl, there is [Code::CutNPaste](http://p3rl.org/Code::CutNPaste). Maybe you can get some inspiration from it. — choroba, Mar 11 '14 at 13:34

I am surprised how few people know what is a copy paste detector (and maybe downvote for that reason) — pihentagy, Mar 11 '14 at 20:48
Requests for tool recommendations are explicitly off-topic on StackOverflow, so guessing that downvotes are out of ignorance is perhaps ill-founded. (That said, I've never heard of duplicate code detection tools being called "copy paste detectors"). — Charles Duffy, Mar 11 '14 at 20:58

This is what comm is for:

comm -12 <(sort file1.txt) <(sort file2.txt)

I've been searching for this myself. Here are some of the results I've found that either claim they do plain text, or someone else claims they do plain text.

MOSS

Clone Dr

Simian

Near Dup

I've also run into some others, such as DuDe (exists several places) and CCfinder but I can't get either of them to compile.

I only post anonymously, so I don't have enough rep to post more than two links, sorry.

Edit: Atomiq worked for me on plain text, that will probably be my go to now
